Reliability of the services assessment for children and adolescents.

OBJECTIVE: This study examined the test-retest reliability of a new instrument, the Services Assessment for Children and Adolescents (SACA), for children's use of mental health services. METHODS: A cross-sectional survey was undertaken at two sites. The St. Louis site used a volunteer sample recruited from mental health clinics and local schools. The Ventura County, California, site used a double-blind, community-based sample seeded with cases of service-using children. Participating families completed the SACA and were retested within four to 14 days. The reliability of service use items was calculated with use of the kappa statistic. RESULTS: The SACA- Parent Version had excellent test-retest reliability for both lifetime service use and previous 12-month use. The SACA also had good to excellent reliability when administered to children aged 11 and older for lifetime and 12-month use. Reliability figures for children aged nine and ten years were considerably lower for lifetime and 12-month use. The younger children's responses suggested that they were confused about some questions. CONCLUSIONS: This study demonstrates that parents and older children can reliably report use of mental health services by using the SACA. The SACA can be used to collect currently unavailable information about use of mental health services.

Mental health service use by Americans with severe mental illnesses.

BACKGROUND: The aim of this study was to determine the patterns and determinants of service use in severely mentally ill persons drawn from the National Institute of Mental Health Epidemiological Catchment Area (ECA) program, a community-based epidemiologic survey. This information provides a baseline against which to track ongoing changes in the US mental health service system. METHODS: Severe mental illness (SMI) was defined according to US Senate Appropriations Committee guidelines. Comparisons were made with persons who had a mental disorder that did not meet these criteria (non-SMI). Sociodemographic factors, and 1-year volume and intensity of mental or addictive services use were determined. Differences between those who used services and those who did not were examined using logistic regression. RESULTS: Persons with SMI differed from persons with non-SMI in most sociodemographic characteristics. A higher proportion of persons with SMI used ambulatory services, but the mean number of visits per person did not differ from the non-SMI population. Persons with SMI comprised the bulk of hospital inpatients admitted during a 1-year period. Several significant sociodemographic determinants of service use were found, with different patterns for general medical and specialty service use, pointing out potential barriers to care. CONCLUSIONS: As health care reform measures continue to be debated, attention to the service needs of the severely mentally ill is of crucial importance. Pre-managed care (pre-1993) baseline service use benchmarks will be essential to assess the impact of managed care on access to care, particularly for the severely mentally ill. Periodic collection of epidemiologic data on prevalence and service use would thus greatly facilitate service planning and addressing barriers to receiving mental health services in this population.

Advances in understanding and treating mental illness: implications for policy.

Mental illnesses have a significant impact on public health and contribute to a substantial part of the disability of the general population. Recent research on understanding and treating such illnesses has produced data that can inform policymakers about how to improve the condition of persons who suffer from these illnesses. This paper discusses how this research can be used to inform policy decisions regarding the allocation of community treatment resources and what research is still needed.

Structural issues and policy in the primary care management of depression.

This article reviews problems in the primary care management of depression at the patient, provider, and practice levels. These problems make it difficult for physicians to deliver proven treatments optimally and for patients to adhere optimally. Potential structural and policy solutions are proposed, suggesting that modifications addressed at multiple levels will make it possible to deliver existing treatments more effectively in primary care settings.

Limitations of diagnostic criteria and assessment instruments for mental disorders. Implications for research and policy.

During the past 2 decades, psychiatric epidemiological studies have contributed a rapidly growing body of scientific knowledge on the scope and risk factors associated with mental disorders in communities. Technological advances in diagnostic criteria specificity and community case-identification interview methods, which made such progress feasible, now face new challenges. Standardized methods are needed to reduce apparent discrepancies in prevalence rates between similar population surveys and to differentiate clinically important disorders in need of treatment from less severe syndromes. Reports of some significant differences in mental disorder rates from 2 large community surveys conducted in the United States--the Epidemiologic Catchment Area study and the National Comorbidity Survey--provide the basis for examining the stability of methods in this field. We discuss the health policy implications of discrepant and/or high prevalence rates for determining treatment need in the context of managed care definitions of "medical necessity."

The epidemiology of psychiatric disorders and the de facto mental health care system.

Recent national epidemiologic studies have provided data on the number of people in the United States with mental and addictive disorders. Many of these people receive their care in the general medical care sector. This has important implications for diagnosis and treatment of mental and addictive disorders.

Effects of Medicare's prospective payment system on service use by depressed elderly inpatients.

OBJECTIVE: To determine the effects of Medicare's prospective payment system (PPS) on hospital care, changes in length of stay and intensity of clinical services received by 2,746 depressed elderly patients in 297 acute care general medical hospitals were studied. METHODS: A pre-post design was used, and differences in sickness at admission were controlled for. Data on length of stay and use of specific clinical services were obtained from the medical record using a medical record abstraction form. Care provided on units exempt from PPS was compared with care provided in nonexempt units. RESULTS: After implementation of PPS, the average length of stay fell by up to three days within the different types of acute care settings studied, but this decline was partially offset by proportionately more admissions to psychiatric units, which had longer lengths of stay. Intensity of clinical services increased after PPS implementation, especially in nonexempt psychiatric units. CONCLUSION: Despite financial incentives for hospitals to reduce clinical services under PPS, its implementation was not associated with a marked decline in length of stay, when averaged across all treatment settings, and was associated with an increase in the intensity of many clinical services used by depressed elderly patients in general hospitals.

Who comes to a voluntary depression screening program?

OBJECTIVE: The purpose of this study was to describe who comes to a voluntary depression screening program by analyzing findings from the 1992 National Depression Screening Day. METHOD: Survey results from 5,367 adult volunteers at 345 facilities were analyzed. The authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and treatment history of the respondents. They also estimated the percentage of these individuals who would actually have a diagnosis of major depression (positive predictive value). The main assessment measure was the Zung Self-Rating Depression Scale. RESULTS: Of all participants, 76.6% (N = 4,109) had at least minimal depressive symptoms (score of at least 50 on the Zung depression scale), 53.3% (N = 2,859) had at least moderate symptoms (score of at least 60), and 22.6% (N = 1,214) had severe symptoms (score of at least 70). Few of the depressed respondents were currently in treatment for a mental health problem. The positive predictive value of a screening test diagnosis of depression was between 92.5% and 95.5% when a cutoff score of 60 was used to indicate depression and between 88.7% and 92.3% when a cutoff score of 50 was used. CONCLUSIONS: Voluntary screening tests, as exemplified by results from the National Depression Screening Day, provide a good opportunity for identifying previously unidentified and untreated individuals with depression.

Quality of care for depressed elderly patients hospitalized in the specialty psychiatric units or general medical wards.

BACKGROUND: Studies to assess quality of care have become increasingly important for research and policy purposes. OBJECTIVE: To evaluate the difference in quality of care between elderly depressed patients hospitalized in specialty psychiatric units and those hospitalized in general medical wards. METHODS: We reviewed retrospectively the medical charts of 2746 patients with depression hospitalized in 297 general medical hospitals in five different states. Quality of care was assessed by clinical review of explicit and implicit information contained in the medical records of patients in specialty psychiatric units (n = 1295) and general medical wards (n = 1451). We also used other secondary data sources to determine postdischarge outcomes. RESULTS: We found that (1) a higher percentage of admissions on the psychiatric units were considered appropriate, (2) overall psychological assessment was better on the psychiatric unit, (3) patients were more likely to receive psychological services on the psychiatric wards but more likely to receive traditional general medical services on medical wards, (4) there were more inpatient general medical complications on the psychiatric wards, and (5) implicit measures of clinical status at discharge were better for those on the psychiatric unit. CONCLUSIONS: Although limited by reliance on medical record abstraction and a retrospective study design, our data indicate that the quality of care for the psychological aspects of the treatment of depression may be better on psychiatric units, while the quality of general medical components of care may be better on general medical wards.

Quality of care for depressed elderly pre-post prospective payment system: differences in response across treatment settings.

We evaluated the quality of care for depressed elderly patients (n = 2,746) hospitalized in general medical hospitals (n = 297) before or after implementation of Medicare's Prospective Payment System, focusing on whether the response to time period differed for hospitals that in the post-PPS period had no psychiatric unit, an exempt psychiatric unit, or a nonexempt unit, and by ward placement within hospitals with psychiatric units. Quality of care increased over time, and for most measures of quality of care the level of improvement did not differ significantly across different types of hospitals or by ward placement. The intensity of use of therapeutic services, such as rehabilitation, occupation, or recreation therapy, increased over time, particularly in nonexempt psychiatric units and hospitals without psychiatric units, such that these locations caught up some over time in the level of use of these services to the level for exempt psychiatric units. Several outcomes of care improved over time, and the degree of improvement in the rate of inpatient medical and psychiatric complications and other outcomes was significantly greater for psychiatric units that were exempt post-PPS than for nonexempt treatment locations.

Quality of antidepressant medications prescribed at discharge to depressed elderly patients in general medical hospitals before and after prospective payment system.

This study describes the quality of antidepressant medication use at hospital discharge for depressed elderly inpatients and compares quality of care before and after implementation of Medicare's Prospective Payment System (PPS). The study reviewed data from medical records of 2746 depressed, elderly, hospitalized patients in acute-care general medical hospitals in five U.S. states (pre-PPS period 1981-82; post-PPS period 1985-86). The majority were discharged on antidepressant medication both pre-PPS and post-PPS. After PPS' implementation, sedating medications were used less often in all treatment settings. In general medical wards, a higher percentage post-PPS (24%) than pre-PPS (14%) were discharged 48 hours or less after first starting an antidepressant medication. In both time periods, one-third of patients receiving antidepressant medications were prescribed daily dosages at discharge below recommended, minimum, therapeutic levels, whether treated in general medical wards or psychiatric units. Otherwise, patients previously treated in psychiatric units received higher quality of medication management than those treated in general medical wards. Over time, patients discharged on antidepressant medication were less likely to use sedating medication, suggesting improved quality of care. In general medical wards, however, patients were discharged more rapidly after starting medication, possibly suggesting lower quality of care. A substantial percentage of patients received subtherapeutic dosages of medication or sedating medications, suggesting that improved management of discharge antidepressant medication in the elderly is needed in general medical hospitals.

Quality of care for hospitalized depressed elderly patients before and after implementation of the Medicare Prospective Payment System.

OBJECTIVE: The authors evaluated the impact of Medicare's Prospective Payment System on aspects of quality of care and outcomes for depressed elderly inpatients in acute-care general medical hospitals. METHOD: The depressed elderly inpatients (N = 2,746) were hospitalized in 297 acute-care general medical hospitals. The authors used a retrospective before-and-after design, controlling for differences over time in sickness at admission. Quality of care and outcomes were assessed through clinical review of explicit and implicit information in the medical records; secondary data sources provided information on postdischarge outcomes. RESULTS: After implementation of the prospective payment system 1) a higher percentage of patients had clinically appropriate acute-care admissions; 2) the initial assessment of psychological status by the treating provider was more complete; 3) the quality of psychotropic medication management, as rated by the study psychiatrists, improved; 4) the rates of any inpatient medical or psychiatric complication, of discharge to another hospital or a nursing home, and of inpatient readmission declined; and 5) there was no marked change in the percentage of patients rated by study clinicians as having acceptable overall clinical status at discharge or the rate of mortality 1 year after admission. CONCLUSIONS: After the implementation of the Medicare Prospective Payment System, the quality of care for depressed elderly inpatients improved and there was no marked increase in adverse clinical outcomes. Despite these gains, after implementation the quality of care was moderate at best and over one-third of the patients had unacceptable clinical status at discharge.

Mental health needs of the uninsured.

As many as 37 million Americans have no medical insurance, but no data exist on the mental health needs of community samples of the uninsured. Using interview data from a household sample in Los Angeles, we found that the uninsured had a higher prevalence of serious psychiatric disorder (16%) than those with private health insurance (12%), but had a prevalence similar to those with Medicaid (18%). Access to mental health services among those with a psychiatric disorder was similar in the uninsured (14.5%) and those with private insurance (18%) but was less than those with Medicaid coverage (42%). These results indicate that the uninsured have a great potential need for mental health services and that access might be improved through insurance plans such as Medicaid. However, further study is needed to determine the adequacy and quality of services provided under Medicaid and whether such a plan would improve access for an uninsured population such as the one studied here.

How do HMOs reduce outpatient mental health care costs?

OBJECTIVE: Because previous studies of differences in utilization of mental health care services have had important limitations, it is not clear if their findings that health maintenance organization (HMO) outpatient mental health care costs less than fee-for-service care are due to less access, less intensive care per user, or selective enrollment of healthier people by HMOs. Therefore, the authors used data from the National Institute of Mental Health Epidemiologic Catchment Area (ECA) study to examine differences in the prevalence of psychiatric disorder and differences in the use of outpatient mental health services for adults enrolled in HMO or fee-for-service health insurance plans. METHOD: The subjects were an ECA community sample obtained from East Los Angeles and West Los Angeles. This sample included a large number of Hispanic subjects. The subjects were categorized according to their responses to a 5-item battery on insurance as Medicare enrolles, members of private fee-for-service plans, Medicaid enrollees, members of an HMO, and uninsured. The presence or absence of psychiatric disorders was determined by using the NIMH Diagnostic Interview Schedule. Both users and nonusers of mental health services were studied. RESULTS: The HMO and fee-for-service plans had similar prevalence of psychiatric disorder and similar access to specialty mental health care. However, HMO enrollees had significantly fewer visits per user to providers of specialty care. CONCLUSIONS: The most likely explanation for lower mental health care costs in HMOs is a less intensive style of care for a comparably sick population.

Psychiatric disorder in male veterans and nonveterans.

Prevalences of Diagnostic Interview Schedule/DSM-III psychiatric disorders for male veterans and nonveterans from four war eras were estimated using data from over 7500 male community respondents interviewed by the Epidemiologic Catchment Area program at five geographic areas across the country. Veterans serving after Vietnam (Post-Vietnam era) had greater lifetime and 6-month prevalences of psychiatric disorder than their nonveteran counterparts, whereas the reverse tended to be the case for the Vietnam, Korean, and World War II war eras. Comparisons across war eras revealed a trend for more psychiatric disorder, especially substance abuse, in younger veterans and nonveterans than in older respondents.
